But Tablegate isn't the first incident where they've clashed.

Just weeks earlier, Katy and Russell were sitting on opposite sides of the court at a LA Lakers game at the Staples Center. But although they were sat seats away from each other, neither acknowledged that the other was there.

The news of the incident comes as Katy was pictured looking glum and hiding her face as she emerged from Los Angeles airport, leading to speculation over what caused the upset.

Katy
has also been linked to a string of eligible bachelors since her divorce to Russell, including
Florence + the Machine guitarist Rob Ackroyd and model Baptiste
Giabiconi, before dating John Mayer, 35, on and off since the summer.

The
'Part of Me' singer has previously used her romance and heartbreak as
inspiration for many of her hit singles.
